BMW calls for new hardware each time one of the control arm nuts or bolts is loosened. The factory torque spec is to tighten to a specific torque value plus an additional turn to stretch the bolt. This stretch is extra insurance that the bolt will not loosen. A stretched bolt cannot be re-tightened and will likely fail.
This is a set of hardware for all 4 front control arms on F87 M2, F80 M3, F82, M4, F22 2-series, F30 3-series, and F32 4-series, including RWD and xDrive models.
Included in this set -
2 x 31106885777, upper thrust arm inner bolt*
2 x 31106797237, lower wishbone inner bolt
2 x 33326760668, lower wishbone inner nut
4 x 33306787062, thrust arm and wishbone outer nut
2 x 33326768884, sway bar link nut
*F22/F3X: the nut for the thrust arm is welded to the subframe so no separate part is required.
